President Obama is publicly upbeat, but his strategy in Afghanistan is not working as planned. Has President Karzai lost faith in the US and NATO? Is Pakistan even closer to the Afghan Taliban than previously reported? Also, oil executives get grilled on Capitol Hill as President Obama prepares to address the nation, and Wikipedia eases restrictions on editors tempted to get "naughty" with controversial subjects like George W. Bush.

President Obama told US troops in Florida today that the war in Afghanistan is going well but, in Afghanistan itself, there are signs of trouble. As the struggle for Kandahar faces delay, former aides say President Karzai has lost confidence in the US and NATO, and wants to deal with the Taliban. Pakistan's support for the Afghan Taliban is reportedly even deeper than known before. The discovery of vast mineral resources could be good news or bad. We hear from reporters on the ground and in Washington, where Middle East Commanding General David Petraeus fainted during a Senate hearing.

In eight years, Wikipedia has become the world's fifth most popular website, with the goal of providing free access to "the sum of all human knowledge." It relies on millions of online volunteers to write, edit and police entries for accuracy. But lately, more volunteers are quitting than signing on. Today, it announced it's making it easier to edit some of its most controversial articles.
